Most American collectors have never heard of Mdina glass, but it's a popular collectible in Europe. Michael Harris: Mdina Glass and Isle of Wight Studio Glass by Mark Hill (Mark Hill Publishing, P.O. Box 36041, London SW16 5XL, England, MarkHillPublishing.com, 2006, 158 pages, about $52) is a small but fact- and picture-filled book. You need it to identify this modern studio glass made since the 1960s. The book is not available in the United States, so we ordered it online from the author and paid through PayPal. It saved the exchange charges.
